Current LED lamps generally use aluminum alloy with inserts as heat sinks. The heat sink usually reaches a higher temperature and cannot achieve the desired effect of heat dissipation. So far, it is a problem that disturbs the heat dissipation of the LED lighting industry. The led street lamp radiator should combine the following aspects

1. Break through the problem of unsatisfactory heat dissipation effect of the existing finned aluminum radiator. Most existing ceiling lights use aluminum with fins as a heat sink. The heat dissipation effect of this type of heat sink is not ideal, and the heat sink usually reaches a higher temperature.
2. Insulation and heat dissipation plastics are used instead of aluminum alloys to make heat sinks. Korea has developed an LED insulation and heat dissipation plastics in 2009. While keeping the heat dissipation capacity equal to that of aluminum alloys, the heat radiation capacity is increased by 4-8 times. The LED heat sink made of this heat dissipation material can greatly improve the overall heat dissipation effect.
3. Adopt liquid convection principle to provide a ceiling lamp with good heat dissipation performance. Use the heat absorbed by the cooling liquid in the liquid storage tank mounted on the lampshade from the lampshade, and at the same time use the natural convection of the cooling liquid between the two liquid storage tanks of different heights to dissipate the heat absorbed by the cooling liquid from the lampshade , So that the lampshade of the ceiling lamp is well cooled.
4. Can be flexibly rotated, easy to install. Since the coolant convection pipe connected between the two liquid storage tanks has a bellows structure, and the bellows structure is expandable and bendable, it does not hinder the flexible rotation of the lamp cover and is also easy to install.
